I didn't expect there are so many responses in such short time.Much appreciated for all your guys reply.
the length of my driveway is 30M and width is 3M, hence totally just around 100 m2. They said crushed rock cost them around 2500 and 1500 for labor to put it down.
Before signing up the contract, we gave them all sites plans and they know it is subdivision land with long driveway. They should have considered this situation and give us quotation completely.otherwise I have had gone with the other builder even the quotation higher than them
Now we are afraid more and more post variation might be received due to this or that reasons. We can't afford as the bank lend us based on contract price.
Now they said they can waive AUD 1500 for labor, but we still must pay aud 2500 for crushed rock.
But we think it is still very high as per your guys experience.
